I smashed the screen of my iPad Mini 2 a few years ago, the damage was minor but I chose to get it repaired professionally. The screen works for the most part but certain areas such as the top right hand corner and individual keys on the onscreen keyboard on landscape mode are unresponsive.
I have not damaged the replacement screen in any way, so what could be causing this issue considering most of the screen works perfectly. It’s frustrating because the device still works pretty well given it is almost 7 years old, but it is annoying having to turn the iPad around to use certain functions.
